Overview

Is it possible to attach money to an email?
So that it cannot be simply copied?
In the internet where everybody can listen?
Can that be secure?

Other than with common electronic transactions electronic money shall behave much more like usual money. We want it to be anonymous, indistinguishable, yet traceable in case of emergency. And one shall not be able to duplicate it.

Topics include

Electronic money: What's that?
Applications
Basics in cryptography
Signatures
Solutions
Do it yourself!

We deal with a completely new kind of money. Many have already bought things in the internet and know various of ways how the article is payed then. Mostly, the money is transferred using one's bank account or via a credit card. Electronic money to the contrary consist only of bits... The right bits at the right moment are money for the recipient. He can deposit it at his bank account just like ordinary money. And the bank will not know where the money comes from. Similarly, the sender's bank will not know where the money goes to. And despite all this you must not be able to copy electronic money and just pay a second time with the very same bits. How to achieve all this shall be worked out in this workshop.

Extent

Equivalent 2+1 SWS.
